- State the following is true or false. If false, explain why."Empty parentheses following a function name in a function definition indicate that the function does not require any parameters to perform its task."c++ the following function header is for a function thattakes two pointers to double-precision, floatingpoint numbers x and y as parameters and does notreturn a value.void exchange( double *x, double y ) Select one: True FalsePlease fill in the blanks for the following statements: If a function does not return a value its return type is __________________.
- 36- Consider the following function call: min(x, y) What is the function name and what is the first argument? a. The function name is min and the first argument is x b. Functions in Python don't have names (they're anonymous functions), but the first argument is x. c. The function name is min, but you need to see the function definition to determine the arguments. d. Functions in Python don't have names (they're anonymous functions) and you need to see the function definition to determine the arguments2. If a function have all the default arguments but still some values are passed to the function then _________.(Numerical) Heron’s formula for the area, A, of a triangle with sides of length a, b, and c is A=s(sa)(sb)(sc) where s=(a+b+c)2 Write, test, and execute a function that accepts the values of a, b, and c as parameters from a calling function, and then calculates the values of sand[s(sa)(sb)(sc)]. If this quantity is positive, the function calculates A. If the quantity is negative, a, b, and c do not form a triangle, and the function should set A=1. The value of A should be returned by the function.
- Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)(Practice) For the following function headers, determine the number, type, and order (sequence) of values that should be passed to the function when it’s called and the data type of the value the function returns: a. int factorial(int n) b. double volts(int res, double induct, double cap) c. double power(int type, double induct, double cap) d. char flag(char type, float current, float time) e. int total(float amount, float rate) f. float roi(int a, int b, char c, char d, float e, float f) g. void getVal(int item, int iter, char decflag, char delim)(Numerical) a. The following is an extremely useful programming algorithm for rounding a real number to n decimal places: Step 1: Multiply the number by 10n Step 2: Add 0.5 Step 3: Delete the fractional part of the result Step 4: Divide by 10n For example, using this algorithm to round the number 78.374625 to three decimal places yields: Step1:78.374625103=78374.625 Step2:78374.625+0.5=78375.125 Step3:Retainingtheintegerpart=78375Step4:78375dividedby103=78.375 Using this algorithm, write a C++ function that accepts a user-entered value and returns the result rounded to two decimal places. b. Enter, compile, and run the program written for Exercise 11a.
- Q1)Use C code to do ,based on the formula provided below, write a function called myFormula which takes two integer values, B and C. Calculate A which acts as an output parameter. A=BCFor this c++ homework fill in the code Use functions and function declarations (headers) to calculate the payment schedule for a loan. Read from the user: initialLoan, annualInterest, MonthlyPayment Create a loan payment function based on the 3 params above. For each month, print on one line, for each month#: Month, Balance, Payment, PaidOnBalance, Interest, Total Int. Paid Until the monthbalance (currentBalance)<=0 At the end of every year (12 months), draw a line of 65 '$' characters. If the MonthlyPayment < 1st month's monthlyInterest, reject the payment code: #include <iostream>using namespace std; // make a header here for drawline // make a function called printLoanPayments that// takes in the loanAmount, annualInterest, and monthly payment// (each of the above are doubles) // print a header for multiple columns// convert annualInterest to monthly interest // keep updating the current balance// keep updating the total Interest paid// calculate the…
